Question

Define the terms - amplitude, time period and frequency of a vibrating body

Answer 1

amplitude=the maximum distance from the point of a wave is known as amplitude

=the time taken by the vibrating  object to complete one vibration

the no of vibrations in one second is called frequency

Answer 2

hey mate
I hope it's useful
Amplitude:the maximum displacement from the mean position during an oscillation.
time period: the time taken by an oscillating body to complete one oscillation is called its time period.
frequency: the number of oscillation of vibration the complete by an oscillating body in one second is called its frequency.
